Solution Overview

Problem

Existing medical imaging technologies suffer from display shake during scanogram capturing, which occurs when a line indicating the capturing range is superimposed in real time on a subject image, leading to instability in the display.

Innovation Solution

An information processing apparatus that continuously acquires image information and controls the display of a line indicating the capturing range by comparing the position of the line at the current time with that of a previous image, only updating the display if the difference exceeds a threshold value, thereby reducing display shake.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a line indicating the capturing range is displayed by being superimposed on a subject image in real time, then the operator can check the capturing range while following the subject movement, but display shake is likely to occur in the display image

Engineering Contradiction:
Improveoperator ability to check capturing rangeVSAvoiddisplay image stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent applies periodic action by updating the line position only at specific intervals when the bed reaches predetermined positions (scanogram start position and scanogram end position), rather than continuously updating in real-time. This periodic update approach maintains the operator's ability to check the capturing range while preventing display shake caused by continuous real-time updates during bed movement.

Inventive Principle:
Principle #19Periodic action

2Reliability

If the line position is updated continuously in real time, then the capturing range display follows subject movement, but unnecessary updates cause display shake

Engineering Contradiction:
Improvecapturing range display accuracyVSAvoidprocessing time for unnecessary updates
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs periodic updates only at predetermined bed positions (scanogram start and end positions) rather than continuous real-time updates. This reduces processing time by eliminating unnecessary updates during bed movement while maintaining reliable capturing range display at critical moments.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The patent performs preliminary action by pre-determining the update timing based on bed position triggers. The line position is updated in advance at specific predetermined positions before the actual scanogram capturing begins, ensuring accurate display without requiring continuous real-time processing.

Inventive Principle:
Principle #10Preliminary action

AI summary

Provided are an information processing apparatus, a medical image capturing apparatus, an information processing method, and a program capable of suppressing display shake caused by display of a line indicating a capturing range of scanogram capturing, as compared with a technology of the related art. An information processing apparatus (10) includes a display controller that continuously acquires image information obtained by optically capturing a subject in a decubitus state on a bed while performing control to display a first line in a case where a difference between a position of the first line corresponding to a position of a predetermined part of the subject in an image indicated by the image information at a current point in time and a position of a second line corresponding to a position of the above-described predetermined part of the subject in an image indicated by the image information in a most recent past exceeds a predetermined threshold value.
